Summary
Cadherin proteins control cell connections, crucial for health. Defects in these cell adhesion molecules cause various inherited human disorders, highlighting their importance.
Area of Science:
- Molecular Biology
- Genetics
- Human Health
Background:
- Cadherins are vital for cell-cell adhesion, playing a critical role in human health and disease.
- Over 115 human genes encode cadherins and related proteins, with known links to numerous inherited disorders.
Purpose of the Study:
- To explore the diverse roles of cadherins in human health and disease.
- To investigate the physiopathological mechanisms underlying cadherin-related disorders.
- To understand how cadherin defects lead to a wide spectrum of phenotypes.
Main Methods:
- Review of existing literature on cadherin function and associated disorders.
- Analysis of genetic data, including exome and genome sequencing.
- Comparative study of different cadherin types (classical, desmosomal, atypical).
Main Results:
- Defects in 21 cadherin proteins are linked to human inherited disorders.
- Affected conditions include skin, hair, cardiac, sensory (deafness, blindness), and psychiatric disorders.
- Emerging sequencing technologies are expected to reveal more cadherin involvement.
Conclusions:
- Cadherins are essential for maintaining tissue integrity and function.
- Cadherin defects contribute to a broad range of human diseases.
- Studying these disorders provides insights into cadherin function, adhesion mechanics, and signaling pathways.

01:25Structure of Cadherins
The cadherins were one of the first cell adhesion molecules discovered; the term “cadherins” is based on their calcium-dependent adhering properties. The first cadherins discovered on the epithelial, neuronal, and placental cells were named E-cadherin, P-cadherin, and N-cadherin, respectively. These classical cadherins share sequence and structural similarities. Other cadherins, including those involved in cell signaling, are grouped into non-classical cadherins. This diversity of cadherins...
01:19Cadherins in Tissue Organization
The cadherins are a superfamily of cell adhesion molecules comprising over 180 variants, with specific tissues expressing a particular combination of cadherin types. Cadherins generally exhibit homophilic binding; i.e., cadherins on one cell bind to cadherins of the same or closely related type on another cell. Thus, cells of the same type have a specific affinity to bind to each other and sort themselves into clusters to form tissues.

01:24Adherens Junctions
Strong contact points between adjacent cells anchor them to each other, forming tissues. Such anchoring junctions are of two types – adherens junctions and desmosomes. Adherens junctions are abundant in tissues such as epithelium and endothelium, forming a continuous zone of adhesion called the adhesion belt. In other tissues, such as heart muscle, they appear as clusters, linking the cells to produce coordinated heart muscle contraction.

01:05Desmosomes
The term desmosome derives from the Greek words "desmo" and "soma" meaning "adhesion bodies." This structure was first observed during the late 1800s and described as small, dense nodules in the epidermis. Desmosomes are button-like structures that help form an interlinked network of intermediate filaments across the cells. These junctions are essential to hold cells together under mechanical stress and to maintain tissue integrity. Desmosomes are multi-protein complexes comprising desmosomal...
03:14Notch Signaling Pathway
The Notch signaling pathway is a major intracellular signaling pathway that is highly conserved over a broad spectrum of metazoan species. It stands unique from other intracellular signaling mechanisms in animals because notch protein itself acts as the receptor as well as the primary signaling molecule.
The Notch gene came into the limelight in 1914 after the discovery that its mutation in Drosophila melanogaster leads to a serrated (or "notched") wing margin phenotype. It was not until 1985...

01:23Catenins
Catenins are characterized by multiple binding domains and dynamic structures that allow them to function as linker proteins in cell junction complexes. All catenins, except α-catenin, contain a characteristic protein sequence called the armadillo repeat and are therefore also called armadillo proteins.
